Description
本創作係有關於一種具有油氣控制節流構造之活性過濾碳罐，特別是指可延長活性過濾碳罐使用壽命的創作。This creation is about an activated carbon filter tank with oil and gas control throttling structure, in particular, it can extend the service life of the activated carbon filter tank.
早期汽機車油箱的對流孔都是直接連通至外界空氣使油箱內壓力能夠平衡，因此油箱內的汽油揮發後，會直接由該對流孔散逸至大氣中，但是揮發的油氣中含有大量的碳氫化合物，因而當油氣散逸至大氣時不僅會造成空氣污染，吸入人體中也會對健康造成危害。The convection holes of the fuel tanks of early steam locomotives are directly connected to the outside air to balance the pressure in the fuel tank. Therefore, after the gasoline in the fuel tank volatilizes, it will directly escape from the convection holes into the atmosphere, but the volatile oil and gas contains a lot of hydrocarbons Chemical compounds, so when the oil and gas escapes into the atmosphere, it will not only cause air pollution, but also cause health hazards when inhaled into the human body.
為解決此問題，業者將油箱的對流孔連接至活性過濾碳罐中，當油氣揮發時，經過該碳罐的活性碳過濾層以過濾淨化而去除大部分的碳氫化合物，再排出至大氣中，以減少排出的汙染物。To solve this problem, the industry connects the convection holes of the fuel tank to the activated carbon filter tank. When the oil and gas volatilizes, it passes through the activated carbon filter layer of the carbon tank to filter and purify to remove most of the hydrocarbons, and then discharged to the atmosphere To reduce pollutants discharged.
但是當汽機車靜止不啟動時，油箱內的汽油是持續揮發的，長久以來，揮發的油氣也是非常可觀而造成浪費的，因此有中華民國新型專利第M528787號「過濾裝置」，該案將碳罐進一步連接至化油器及油氣控制閥，當汽機車啟動時，透過該油氣控制閥產生負壓而將油箱中揮發的油氣吸入該化油器，而與油箱中的汽油併同空氣閥進入的空氣混合成混合燃料氣而進入引擎中使用，達成油氣回收再利用的效果。However, when the steam locomotive does not start, the gasoline in the fuel tank continues to volatilize. For a long time, the volatilized oil and gas is also very considerable and causes waste. Therefore, there is a new type of "filter device" No. M528787 of the Republic of China. The tank is further connected to the carburetor and the oil and gas control valve. When the steam locomotive starts, a negative pressure is generated through the oil and gas control valve to suck the volatile oil and gas in the oil tank into the carburetor, and enter the air valve together with the gasoline in the oil tank The air is mixed into a mixed fuel gas and used in the engine to achieve the effect of oil and gas recovery and reuse.
在該案中，油箱內揮發的油氣是持續不間斷進入碳罐中，因此碳罐中的活性碳過濾層要持續的過濾淨化油氣中的汙染物，而活性碳過濾層不間斷的持續使用造成其使用壽命短，而碳罐的主要成本通常來自於該活性碳過濾層，因而時常更換該活性碳過濾層造成高的使用成本。In this case, the volatile oil and gas in the fuel tank continuously enters the carbon canister, so the activated carbon filter layer in the carbon canister must continuously filter and purify the pollutants in the oil and gas, and the continuous use of the activated carbon filter layer results in The service life of the carbon canister is short, and the main cost of the carbon canister usually comes from the activated carbon filter layer. Therefore, the activated carbon filter layer is often replaced, resulting in high use cost.

參閱第六圖、第七圖及第八圖所示，當該機車供油系統不啟動時，該油箱(10)中的汽油會持續的揮發，並通過該管接部(751)進入該油氣控制節流構造(7)，而當揮發的油氣之壓力小於該第一彈性件(72)的彈性力時，該蓋件(75)的抵面(752)持續抵在該基座(71)的第二抵部(7122)而隔開該管接部(751)與該容置部(113)，因此揮發的油氣無法進入該罐本體(1)中[如第五圖所示]。而當汽油持續揮發，使得油氣的壓力足夠大而克服該第一彈性件(72)的彈性力時，會壓縮該第一彈性件(72)，使該基座(71)位移而將該蓋件(75)的抵面(752)脫離該基座(71)的第二抵部(7122)而接通該管接部(751)及該容置部(113)，使油氣可通過該油氣進口(111)進入該罐本體(1)中，此時進入該罐本體(1)的油氣會由該入口區(114)擴散至該透孔(21)處，之後才由該透孔(21)進入該活性碳過濾區(115)，進入該活性碳過濾區(115)的油氣可透過該第一泡棉層(3)進行初步的過濾，之後由活性碳的該活性碳過濾層(4)過濾大部分的碳氫化合物，再經過該第二泡棉層(5)及該擴散板(6)後，由該通大氣口(121)排放至大氣中，減少碳氫化合物的汙染。而透過在該罐本體(1)置入該隔板(2)，並使該隔板(2)的透孔(21)對應該油氣進口(111)及該油氣回收口(112)之間，提高了該活性碳過濾層(4)的使用效率，且可進一步縮小該罐本體(1)位在該油氣進口(111)及該油氣回收口(112)外緣的體積，以減少該活性碳過濾層(4)的活性碳使用量，另藉由在油氣壓力足夠時才接通該管接部(751)及該容置部(113)，可達到延該活性碳過濾層(4)的使用壽命。Referring to the sixth, seventh and eighth figures, when the fuel supply system of the locomotive does not start, the gasoline in the fuel tank (10) will continue to volatilize and enter the oil and gas through the pipe joint (751) Control the throttling structure (7), and when the pressure of the volatile oil and gas is less than the elastic force of the first elastic member (72), the contact surface (752) of the cover member (75) continues to contact the base (71) The second abutting portion (7122) separates the pipe connecting portion (751) and the accommodating portion (113), so the volatile oil and gas cannot enter the tank body (1) [as shown in the fifth figure]. When the gasoline continues to volatilize, so that the pressure of the oil and gas is large enough to overcome the elastic force of the first elastic member (72), the first elastic member (72) is compressed, the base (71) is displaced to displace the cover The abutment surface (752) of the piece (75) is separated from the second abutment portion (7122) of the base (71) to connect the pipe connection portion (751) and the accommodating portion (113), so that oil and gas can pass through the oil and gas The inlet (111) enters the tank body (1). At this time, the oil and gas entering the tank body (1) will diffuse from the inlet area (114) to the through hole (21), and then from the through hole (21) ) Into the activated carbon filter zone (115), the oil and gas entering the activated carbon filter zone (115) can be preliminarily filtered through the first foam layer (3), after which the activated carbon filter layer (4 ) Filter most of the hydrocarbons, and then pass through the second foam layer (5) and the diffusion plate (6), and then discharged into the atmosphere from the air vent (121) to reduce hydrocarbon pollution. By placing the separator (2) in the tank body (1) and making the through hole (21) of the separator (2) correspond to the oil and gas inlet (111) and the oil and gas recovery port (112), The use efficiency of the activated carbon filter layer (4) is improved, and the volume of the tank body (1) at the outer edge of the oil and gas inlet (111) and the oil and gas recovery port (112) can be further reduced to reduce the activated carbon The amount of activated carbon used in the filter layer (4) can be extended to the activated carbon filter layer (4) by connecting the pipe connection part (751) and the accommodating part (113) only when the oil and gas pressure is sufficient.

參閱第六圖及第九圖所示，當引擎啟動時，透過該油氣控制閥(20)產生負壓，可將進入該活性碳過濾區(115)的油氣自該隔板(2)的透孔(21)中吸出，並經由該油氣回收口(112)排出該罐本體(1)而進入該調節閥(30)，且在進入該調節閥(30)前會先與該空氣閥(40)進入的空氣混合，再與自該油箱(10)中進入該調節閥(30)的汽油混合成混合燃料氣而進入該引擎汽缸(50)中使用，達成油氣回收再利用的效果。Referring to the sixth and ninth figures, when the engine is started, a negative pressure is generated through the oil and gas control valve (20), and the oil and gas entering the activated carbon filter area (115) can be permeated from the separator (2) It is sucked out from the hole (21) and discharged from the tank body (1) through the oil and gas recovery port (112) to enter the regulating valve (30), and it will first interact with the air valve (40) before entering the regulating valve (30) ) The incoming air is mixed with gasoline from the fuel tank (10) into the regulator valve (30) to form a mixed fuel gas, which is then used in the engine cylinder (50) to achieve the effect of oil and gas recovery and reuse.
參閱第六圖、第十圖及第十一圖所示，當供油系統啟動時，該油箱(10)內的汽油會進入該調節閥(30)而在該油箱(10)形成負壓，當負壓大於該第二彈性件(74)之彈性力時，會使該操作件(73)位移使該操作部(732)脫離該第一抵部(7121)而接通該管接部(751)及該容置部(113)，此時空氣會經由通大氣口(121)進入該罐本體(1)，並透過該擴散板(6)均勻分散進入的空氣，再透過該第二泡棉層(5)初步的過濾進入的空氣後，使空氣通過該活性碳過濾層(4)並經由該油氣控制節流構造(7)進入該油箱(10)，形成對流效應，使該油箱(10)內的汽油能持續進入該調節閥(30)，維持該引擎汽缸(50)的運作。Referring to the sixth, tenth and eleventh figures, when the fuel supply system is started, the gasoline in the fuel tank (10) will enter the regulating valve (30) and a negative pressure is formed in the fuel tank (10), When the negative pressure is greater than the elastic force of the second elastic member (74), the operating member (73) will be displaced to disengage the operating part (732) from the first abutting part (7121) to connect the tube connection part ( 751) and the accommodating portion (113), at this time, the air will enter the tank body (1) through the air vent (121), and evenly disperse the incoming air through the diffusion plate (6), and then pass through the second bubble After the cotton layer (5) preliminarily filters the incoming air, the air passes through the activated carbon filter layer (4) and enters the oil tank (10) through the oil and gas control throttle structure (7) to form a convection effect, so that the oil tank (5) 10) The gasoline in the can continue to enter the regulating valve (30) to maintain the operation of the engine cylinder (50).
